WILLIAM MUNRO, OF DAVENPORT, IOWA.

ROAD-CART.

SPECIFICATION forming part of Letters Patent No. 437,503, dated September 30, 1890.

Application filed February 10,1890. Serial No. 339,866. (No mode/1.),

To all whom it may concern:

Be it known that I, WILLIAM MUNRO, a citi zen of the United States, residing at Davenport,in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Sulkies, Road-Carts, or other Two-Wheeled Conveyances; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to 'sulkies or roadcarts and other two-wheeled conveyances, and aims to relieve the jogging motion of the horse, the body to hang level whether loaded at the front end or back end of body, and the jolting when' the vehicle is going over rough ground and obstacles.

The improvement consists of the novel features, which will be hereinafter more fully described and claimed, and which are shown in the annexed drawings, in which- Figure 1 is a perspective view of .a vehicle embodying my invention, showing the body in position by clotted lines. Fig. 2 is a rear View. Fig. 3 is a detail view of the inner ends of the equalizing-levers.

A represents the axle, C the wheels on the ends of the axle, and B the thills Which are connected with the axle. The brackets D, projecting rearward fron the axle, are preferably prolongations of the thill-bars B and su pport the cross bow-spring E, the latter being fiexibly connected at its ends with said brackets D by the shackles F. The approximately- U-shaped bracket G, secured to the thill-bar, has the two equalizing-levers H andl pivoted to its upper ends. The inner ends of the equalizing-levers are connected by the bolt or rivet J, which passes through slots in the said ends. The outer ends of said equalizing-levers are curved upwardly and inwardly and are connected with the ends of the bolsters K and L by the swinging links Ic and Z, respectively. The spring-bar M, secured at its middle to the bow-spring E, has its ends inserted through or otherwise secured to the corresponding equalizing-levers H on the opposite sides of the vehicle. Each side of the vehicle is simila-ly equipped, being provided with bracket G and equalizing-levers H and I. The vehicle-body N (shown by the dotted lines in Fig. 1) is suspended from the curved ends of the equalizing-levers by swiuging links, as shown.

The operation of the equalizing devices is as follows: It must first be borne in mind that the springs E and M are disposed with reference to the levers I so as to exert an upward force on their outer ends to sustain the Weight of the vehicle-body, which is suspended from or otherwise supported on the outer ends of the said equalizing-levers l-I and I. The Weight of the vehicle-body and its occupants has a tendency to depress the outer ends of the equalizing-levers and elevate the inner ends of the equalizing-levers and in opposition to the springsE and M. Thus it will be seen that through the medium of the equalizinglevers the vehicle-body is sustained in a normal position.

Having fully described ny invention, What I claim, and desire to secure by Letters Patent, is-.- a

1. In a sulky, road-cart, or other twowheeled conveyance, the cqmbination, with the thills and two pairs of equalizing-levers, one pair on each side of the vehicle, and the body suspended from the said equalizinglevers, of the bow-spring E, connected at its ends with the thills, and the spring-bar M, having connection at its middle With bowspring E and at its ends With corresponding equalizing-levers on opposite sides of the vehicle, substantially as described.

2. A snlky, road-cart, or other two-wheeled conveyance comprising the axle, the thills, the brackets D and Gr, the equalizing-levers, the body suspended from the curved ends of the said equalizing-levers, the bow-springs E, and spring-bar M, the spring-barM being connected at its ends with corresponding equalizing-levers on opposite sides of the vehicle, and the spring E connected at its ends with the brackets D, substantially as set forth.

In testimony whereof I affix my Signature in presence of two witnesses.

ROBERT MUNRo, C. WHITAKER.
